It's mounted high because it is the top half of a 6 panel video wall that is 9'x9' for our OLED Art Gallery. I connected an extra set of HDMI cables to input two and run it through a video wall controller/scaler to make a perfect 100" 16:9 display.

I can get the panels a little closer together to minimize the two vertical black bars. I can tell you that most folk don't even notice the black bars as the image is stunning and with many scenes the bars are not as noticeable as they are in the image I posted.

I also used 55" B7As with black tape on the silver trim, however, with the all black C7P bezel the video wall will be cleaner and have a smaller frame.

This is not for everyone, but it is a very very cool 100" UHD OLED display and in the very few hours we've had it on display it drew a lot of serious attention.
